I was taught that you must use the plain form of a verb before から. Recently I've noticed that I will use the ます form of verbs. Most often I'm saying ~がありますから instead of ~があるから。 I feel like it's not right but it comes out so naturally. I'm worried that it seems natural because it's become a habit that no one has ever corrected.

I know that you can use ~ですから to end a sentence, so is ~ますから also grammatically correct?

  • Basically, yes. It just makes the sentence more polite. Commented May 5, 2015 at 22:56
  • @Lyle Yes, but it's more complicated than "yes" or "no", so hopefully someone will write a more detailed answer :-)

No, at least not always.

It is correct to use 「~~ますから」 in stand-alone statements expressing a reason-and-result or cause-and-effect relationship.

「[明日]{あす}また[来]{き}ますから、このパソコンはここに[置]{お}いておきますね。」"I am leaving this PC here because I will come back tomorrow again."

It is NOT correct, however, to use 「~~ますから」 followed by 「です」 in an answer stating a reason/cause to a question asking for such.

Person A:「なんでこういう[音楽]{おんがく}が[好]{す}きなの?」"Why do you like this kinda music?"

Person B:「[心]{こころ}が[落]{お}ち[着]{つ}きますからです。」← Incorrect

Person B should have said 「心が落ち着くからです。」"Because it relaxes me."

  • Would be better to say "Yes but" than "No". Specially if the OP is asking about sentences where it is ok to do so.

  • So then as long as I don't use together with です, then it is correct? Are there any other situation where I can't use it that I should be aware of?
